Danfoss ETS 5T10L electric expansion valve, R744 CO2, 5/16 in (7.94 mm) ODM solder, stepper, 140 bar MWP (034G6803)

Part Number
034G6803 · HS 8481.80

Danfoss ETS 5T10L electric (stepper-motor) expansion valve for transcritical R744 (CO2) systems, code 034G6803. In-line valve with 5/16 in (7.94 mm) solder ODM inlet and outlet in Cu-plated stainless steel, 1.0 mm orifice, bi-flow with a linear flow characteristic. Permanent-magnet stepper motor (480 half steps) gives precise CO2 liquid/gas injection control for booster racks, ejector systems and CO2 heat pumps. Rated capacity 7.27 kW (2.1 TR) at R744 conditions. Max. working pressure 140 bar (2030 psig), MaxOPD 120 bar (1740 psig) forward and reverse. Refrigerant and ambient -40 to 80 °C. Driven by a Danfoss EKE-series driver (EKE 1A/1B/1C/100) or EIM 336, ordered separately. OEM P/N 034G6803.

Compatibility

ETS 5T is a driver-controlled stepper valve for transcritical CO2 (R744) — it does not operate stand-alone. Drive with a Danfoss EKE 1A/1B/1C/100 or EIM 336 controller. Verify orifice class (1.0 mm), inlet/outlet ODM size and MaxOPD (120 bar (1740 psig)) against your CO2 application before ordering.
